@ darshanpatel
I was wondering if you can get us a screen shot of your temp folder permissions.
1) You can go to the temp folder with (percent sign)temp(percent sign) (this also should be in something like: Users\<user name>\AppData\Local\Temp ) in windows explorer address bar.
2) choose properties for this folder and go to the security page, that has a bunch of permissions.
Take a screen shot an you can email it to support at genuitec dot com
Thanks!
